| titleOfInvention | Preparation of alpha-amino-epsilon-caprolactam |
| abstract | PURPOSE: To efficiently prepare a compound useful as a raw material for functional polymer material, etc., in a high yield by reacting lysine with an organic tin compound. n CONSTITUTION: Lysine is reacted with an organic tin compound of the formula: R 1 R 2 SnO (R 1 and R 2 are 1-10C alkyl or aryl) in a solvent such as butanol under the ordinary temperature to a increased pressure at 110-180°C for 1-5 hours to provide the objective α-amino-ε-caprolactam. The organic tin compound and the solvent are employed in a molar ratio of 0.001-0.2 and in a weight ratio of 1-50 times based on the lysine, respectively. The organic tin compound includes dibutyl tin oxide. n COPYRIGHT: (C)1991,JPO&Japio |
